The EVAP purge solenoid will need to be used for either the US or JDM version to properly work.

Various automotive resellers offer "automotive Vacuum line caps" If you search "automotive vacuum nipple caps" then a bunch of baby bottle results come back :-/
I know this water line cap fits the smaller nipples on the turbo inlet perfectly Subaru Factory Parts:Motors and Motor Parts:Water Parts:21170AA010, plus it will last forever unlike cheap rubber caps that need replacing every 1-2 years due to dry rot.

Outstanding info about the rubber caps! +11 Great write up!

Just a little tip for some with oem inlet: I cut off the hose barb with a hack saw blade on the inlet tube flush. Then with a bit of permatex at the base of a push pin, Insert the pin so its flush.

Also, If you take the hose barb out of the intake manifold and use a regular screw in plug it cleans up the engine bay a bit more. I just never liked empty/plugged hose barbs on things.
